I'm installing two sets of kc lights and my plan is to have my switches on the pillar on the drivers side. I took a look and I don't know where to go through the firewall with the wires. I have a 2013 jkur with a manual transmission.

The jeep is one of the easiest vehicles for this......
In each upper corner of the firewall, (viewed from the engine bay) is a
large foam-filled pocket. Simply tape your wires to a straightened coathanger and poke it through.

I dont know if the 2013 is same as 2008 but if it is, if you look under hood above and right of master cylinder is a hole with rubber plug in it. hole is about 1/2" to 3/4" and if you put a coat hanger down it you can easily feed wires through it. If you plan on adding future accessories, consider installing the SPOD system under your hood. It makes life easy. Comes with a 6 switch pod or 4 switch with compressor pod that installs above your rear view mirror. you only have to feed one wire through firewall. box mounts easily under hood, you just plug accessories into it. It has relays and fuses and wires directly to battery so you dont have a jungle of wires attached to battery or fuse box. can send pictures if interested
